The potassium channel FaTPK1 plays a critical role in fruit quality formation in strawberry (Fragaria × ananassa).

ABSTRACT: Potassium (K⁺ ), an abundant cation in plant cells, is important in fruit development and plant resistance. However, how cellular K⁺ is directed by potassium channels in fruit development and quality formation of strawberry (Fragaria × ananassa) is not yet fully clear. Here, a two-pore K⁺ (TPK) channel gene in strawberry, FaTPK1, was cloned using reverse transcription-PCR. A green fluorescent protein subcellular localization analysis showed that FaTPK1 localized in the vacuole membrane. A transcription analysis indicated that the mRNA expression level of FaTPK1 increased rapidly and was maintained at a high level in ripened fruit, which was coupled with the fruit's red colour development, suggesting that FaTPK1 is related to fruit quality formation.
